* Nuclear reactions release a million times more energy, as compared to hydro or wind energy. Hence, a large amount of electricity can be generated. Presently, 12-18% of the world's electricity is generated through nuclear energy. * The biggest advantage of nuclear energy is that there is no release of greenhouse gases (carbon dioxide, methane, ozone, chlorofluorocarbon) during nuclear reaction. The greenhouse gases are a major threat in the current scenario, as they cause global warming and climate change. As there is no emission of these gases during nuclear reaction, there is very little effect on the environment. * The burning of fossil fuels result in emission of the poisonous carbon dioxide. It is a menace to the environment as well as human life. There is no release of carbon d-oxide at the time of nuclear reaction. * Nuclear reactors make use of uranium as fuel. Fission reaction of a small amount of uranium generates large amount of energy. Currently, the high reserves of uranium found on Earth, are expected to last for another 100 years. * High amount of energy can be generated from a single nuclear power plant. Also, nuclear fuel is inexpensive and easier to transport.

What are the Disadvantages of Nuclear Energy?

* Nuclear energy can be used for production and proliferation of nuclear weapons. Nuclear weapons make use of fission, fusion or combination of both reactions for destructive purposes. They are a major threat to the world as they can cause a large-scale devastation. * Though large amount of energy can be produced from a nuclear power plant, it requires large capital cost. Around 15-20 years are required to develop a single plant. Hence, it is not very feasible to build a nuclear power plant. The nuclear reactors will work only as long as uranium is available. Its extinction can again result in a grave problem. * The waste produced after fission reactions...

...THE advantages and disadvantages of Nuclearenergy
Day after day, the energy required in the world increases. Fossil fuels have been used for energy since the outset of the last century. The burning of these fossil fuels over the years has caused the earth’s temperature to increase. Some countries are concerned about this problem, and tend toward finding alternative power sources.
Iran choosesnuclearenergy to decrease poison gases, but this choice has met with the disapproval of many countries like the European Union, USA and Israel fearing an Iranian nuclear weapons program. In my opinion, Iran is entitled to make a beneficial and safely maintained nuclear power station. Nuclear power has a lot of important advantages which I will talk about it in the context of nuclear power production.
The first nuclear power station was established in England in 1956. Nuclear power is generated by using uranium metal, which is mined in various parts of the world.
Some military aircraft carrier and ships use nuclear power for engines.
Nuclear power produces around 12% of the world energy required, and produces large amounts of energy from small amounts of fuel, without the comparative pollution produced by...

...Much of the worlds energy is produced from Uranium. This energy is commonly referred to as "nuclearenergy" because uranium reacts in nuclear reactors to form heat. When fossil fuels are used for heat, they are just simply burned instead of reacted, so they create only mediocre amounts of heat for the plant. Nuclear power is responsible fore over 11% of the worlds energy, without the enormous amounts of coal or the pollution that fossil fuels cause. Natural uranium is only 0.7%"uranium-235, which the uranium that undergoes fission in this type of reactor. The rest of the uranium is uranium-238, which does not react almost at all, and is only mixed in with the uranium-235, because it is too expensive and a waste of time to separate from it. Although that was the kind of Uranium that was used in plants in the past, most plants currently use enriched uranium, which has a much higher composition of the isotope uranium-235, making the plant much more efficient.
Nuclearenergy has proved to be both reliable and safe to use, not to mention very efficient, especially as a power source. An important reason as to why we often use this nuclearenergy is because of all of its advantages over conventional energy sources. Nuclear power plants only need to be refueled once a year, an obvious...

...NUCLEARENERGY AND SAFETY
Consumption of energy is increasing nowadays so nuclearenergy has very importance for energy needs. Nuclearenergy is produced naturally and in man-made operations under human control and it is a thriving global industry. A total of 435 nuclear power plants are operating around the world in 30 countries. Also ,nuclearenergy has some advantagesNuclearenergy has the lowest impact than fossil fuel energy on environment because nuclear plants don't emit harmful gases and require a relatively small area for production.
If mistakes don’t occur , there are no significant adverse effects to water , land and air resources . However , nuclearenergy is so dangerous when accidents occur in nuclear plant ,problem of storing nuclear wastes occur and nuclear power contributes to the proliferation of nuclear weapons. For all these reasons , nuclearenergy is a safe source of energy.
There are many reasons that show nuclearenergy is more dangerous than conventional energy. First reason is nuclear accidents. When something...

...Thatcher once cited.” A world without nuclear weapons would be less stable and more dangerous for all of us.”
In the article “Get real: nuclear power is in your future” Allan Kupcis argues that nuclear power is a necessity to maintain “the backbone of any economy.”
Thus, in our day to days living, we seem to ask ourselves about what is meant by the term "NuclearEnergy." Some will give the right concept of thenuclearenergy but others will not. It all depends with the knowledge one has about the nuclearenergy. In this research paper, I will write on how nuclearenergy arise paying emphasis on the advantages and disadvantages and past cases in the nuclear arena.
While nuclear power is much in the news right now because of the recent accident in Japan. The Fukushima No. 1 nuclear plant disaster has made Japan reconsider the role of nuclear power in its future.
This is an important debate; however, it tends to bypass a major issue at the heart of nuclear power. The major issue is whether or not limitless energy resources are a good thing for our society and planet. Clearly speaking, new sources are needed in order to maintain the current standard of living in first world countries. Many third world...

...Essay “Use of NuclearEnergy: Safe or Not?”
23 Aug
Most countries today are becoming more and more dependent on nuclear power as a source of energy because of its high energy output and the availability of uranium used for fuelling nuclear reactors that generate power to provide electricity in households. Although using nuclear power as a source of energy has benefits like this, the danger posed by using nuclear power is very eminent. This was demonstrated in the recent Fukushima daiichi nuclear reactor crisis wherein the reactors as of March 24, 2011 at Fukushima emitted 30,000 to 110,000 TBq of Iodine 131 much higher compared to Chernobyl’s 760 PBq or 400 kg of I-131, 85 PBq Cs-137 (Shimbun, 2011). Another widely known nuclear reactor accident was the Chernobyl disaster that occurred on April 26, 1986 (Black, 2011).
Threats not only exists in accidents like the ones mentioned, but also threats exists not only from terrorists but also from other countries who have acquired or made nuclear weapons. An all out war will probably see the use of nuclear weapons against each nation’s enemy resulting in a nuclear holocaust. Millions of people will die not only from the initial explosions of the nuclear bombs but also from the following nuclear fallout that...

...Advantages and disadvantages of using nuclear power
For many decades the use of nuclear power has provoked incessant debates among various groups of people. Several scientific studies have shown that nuclear power is not nearly as beneficial to society as it might be imagined. But on the contrary, the use of nuclear power can be rather dangerous.
There are some positive aspects of nuclear power as a source of energy. Firstly, nuclear plants have large production capacity, so it can satisfy the needs of many people. That is why it is very efficient to use nuclear power stations in countries with a big population. Secondly, the production of nuclearenergy does not pollute the environment as it does not release harmful gases into the atmosphere. Moreover, with the uranium and plutonium long refinery run, nuclear ores can be an adequate substitute for fossil fuels that become increasingly scarce. Thirdly, nuclearenergy can be used by countries which do not have enough natural resources to meet all their needs and provide them with enough amount of energy.
On the other hand, there are certain drawbacks of nuclearenergy use. First of all, nuclear power stations imply certain risks because the technology of...
